Essentially, a cloaked version of the standard Gargoyle, the Wraith is a unique strain of Gargoyle that have evolved, or rather, mutated, into developing special light bending pigmentation in their skin cells. This allows them to quickly produce patterns and displays across their body that renders them nearly invisible to the human eye. Thermal Sights, Perception and the Commando's Heightened Senses will allow the user to see through their ruse. Flares cast such an illuminating glow that it overloads the creatures camouflage mechanisms, allowing Marines to see it.
